Polypropylene (PP) is a type of proolefin that is a little harder than polyethylene. Polypropylene is a commodity plastic with low density and resistant to high heat. Among the uses of polypropylene, we can mention the use in packaging, automobiles, consumer goods, medicine, and cast films, and its chemical formula is (C3H6)n.
Polypropylene (PP) is divided into two categories: polypropylene homopolymer and copolymer. In the following, they have been examined:
Polypropylene homopolymer
They are thermoplastic resins that are produced through the polymerization of propylene with Ziegler-Natta catalysts. Homopolymers can be used in various processing technologies such as injection molding, blow molding, film, fiber, sheet extrusion and thermal forming.

Polypropylene copolymer
Copolymers have a second monomer of ethylene, which increases the impact strength compared to polypropylene homopolymer. The key properties of polypropylene copolymer are high impact strength, good chemical resistance, better resistance to cracking at low temperatures and increased flexibility.
